PSU diff

What’s new with Oracle database 12.2.0.1.190416 versus 12.2.0.1.190716

There are a couple of underscore parameters changed from spare to named ones.
It’s interesting to see that in sysstat, ‘spare statistic 2’ changed to ‘cell XT granule IO bytes saved by HDFS tbs extent map scan’. This obviously has to do with big data access via cell servers. What is weird is that this is the only version where this had happened.
